I'm heading out the door
I think it's sad if s dog has no training, this really limits your communication ability and guidance. A biggy is the photo shoot "can he sit there?" "I can try," is usually what I hear. "Does he know how to sit?" And no sooner is it out of my mouth when the owner is applying pressure to their dogs hind end in attempts to sit their dog. This is when I say "let's just let him decide what he wants to do." And I mean it, I'm not being sarcastic. The dog will do what he wants and I will get the shot.
For starters, I think every dog should first know their name. You'd be surprised how many don't. Then to come when called, sit, down, stay and no bolting out open doors. So that is the bare minimum that I like to see. Of course the sky is the limit and it's not all verbal cues that they learn. Dogs can learn hand signals, body signals and linked behaviors. They are pretty amazing actually. But like I said it takes commitment; if you give that commitment you will open up a whole world of communicating and canine behavior.
